He served on the forestry faculty at The University of California before being called to work as chief of the section forest measurements, U.S. Forest Service.^[2] His interest in statistics led him to an affiliation with R.A. Fisher, and Schumacher led early advances to adopt statistical methods in forest inventories and silvicultural research.^[3] He joined the faculty of the Duke Graduate School of Forestry as one of its original seven faculty members.^[4] He co-authored textbooks on forest mensuration and sampling with other notable forest biometricians Donald Bruce^[5] and Roy A.
